Query the display's HDR min/max luminance and feed those values into the post-processing pipeline and shaders. - Add SwapChain::QueryDisplayHDRCapabilities(), include dxgi1_6, and call it during swapchain creation and resize to populate g_backend_info.hdr_max_luminance_nits and hdr_min_luminance_nits. - Extend BackendInfo with hdr_max_luminance_nits and hdr_min_luminance_nits. - Add hdr_max_luminance_nits/min to the built-in uniform block and fill them in PostProcessing::FillUniformBuffer so shaders can access actual panel values. - Update AutoHDR.glsl to use the reported hdr_max_luminance_nits (with a fallback to HDR_DISPLAY_MAX_NITS) when computing the auto-HDR white scaling. This enables more accurate AutoHDR tonemapping by using the display's real luminance capabilities when available.
